Here is a great deal on an Optiplex we modded out for performance over looks. This PC can play AAA and eSports games (medium settings for best experience). We even added an M.2 SSD, so you can enjoy the speeds of a modern-day gaming PC. 16GB of DDR4 RAM allows you to multitask or even play more RAM-demanding games. WiFi is included. Windows 10 Pro is installed, tested, and activated.
